Why do I need to re-enter my BlackBerry
ID login information?

After a certain amount of time passes, if you are not actively using the app or service that supports BlackBerry
ID, you might be prompted to re-enter your login information. For example, you might be prompted to re-enter your BlackBerry
ID before you download apps from the BlackBerry App World storefront.

If you change any of your BlackBerry
ID information, if you delete all the data on your smartphone or tablet, or if you update your BlackBerry
Device Software on your smartphone, you might also be required to re-enter your BlackBerry
ID.
